Compound III-V materials are formed when atoms from group Illb of the periodic table combine with atoms from group Vb. The resulting com pounds are both crystalline and semiconducting and contain an equal proportion of both atom types. The Indium antimonide crystal has been used for infrared applications and for the radiation detector applications. Thin films of InSb with a thickness of about 0.12 micrometer are prepared onto well-cleaned glass substrates by employing an e- beam evaporation process. Indium Antimonide thin films are grown onto well cleaned glass substrates at room temperature on cleaned glass substrate in Hind Hivac- Vacuum Coating unit under a vacuum better than 10-5 Torr. X-ray diffraction studies confirm the polycrystalline of the films and the films show preferential orientation along the (111) plane. The particle size found to about 1100 micrometer of thin film. In this paper we present some of our results concerning the synthesis and crystal growth of indium antimonide compounds . To carry out the synthesis of InSb a suitable mixing furnace was designed and fabricated.

Methods for removal of trimethylamine, the main molecule responsible for the foul odor associated with seafood, were tested from two perspectives. Perception trials revealed that a common hand soap and corn starch were effective at reducing the fishy odor resulting from trimethylamine, while a soap specially formulated to remove fish order was not effective. Quantitative chemical analysis of the amount of trimethylamine persisting after washing revealed that corn starch, hand soap, and a soap specially formulated to remove fish odor were not more effective than water alone. Taken together, these results reinforce the importance of conducting both perceptual and chemical analyses, while also calling into question what the best proxy for human skin is in these types of studies.

The present study is an attempt to examine the relationship between academic
delay of gratification and dispositional orientation variables. Sample for the
study includes 60urban students ( 30 boys
and 30 girls ) of class XI of a junior
college in S.R. Nagar, Hyderabad, Telangana, India. The data for measuring
delay of gratification is collected using Academic
Delay of Gratification Scale (ADOGS) for college students prepared by
HeferBembenutty (1997). Dispositional optimism of the students is measured by
collecting data using theRevised Life Orientation Test Scale (LOT-R) for
college students prepared by Scheier, Carver and Bridges (1994). For data
analysis, Pearson’s Product-Moment Correlation coefficient and Point-biserial
correlation coefficients are calculated using SPSS ver.20. The significance of
the test is calculated for the level of significance α at 0.01. The findings of
the study reveal positive andmoderatelystrong relationship between academic delay
of gratificationand dispositional optimism. Boys are found to possess significantly
less academic delay of gratification when compared to girls.No role of gender
is found on the variable dispositional optimism.

The study determined gender
variation on cardiopulmonary parameters- blood pressure, pulse rate, respiratory
rate and peak expiratory flow rate of residents in gas flaring communities
compared with non-gas flared communities. The ex post facto study carried out
using a stratified random sampling method involving five hundred and four (504)
residents in the gas flaring communities and five hundred (504) in the non -
gas flaring communities comprising 564
males and 444 females. Samples for this study were taken from five states in
the South-South geopolitical states of Nigeria. The electronic blood pressure
kit was used to measure blood pressure and respiratory rate while the peak flow
rate was measured with a peak flow metre and respiratory rate was measured
manually. Data generated were expressed as mean ± SD. Significance difference
between means was determined by student t-test and one-way analysis of variance
(ANOVA). SPSS 20 software was used for statistical analysis. A level of p≤0.05
was accepted as significant. Findings indicate that mean diastolic pressure was
higher in males (10.96%) than females (5.05%). The pulse rate (36.07%) and the
respiratory rate (19.38%) of the female residents in the gas flared
environments was significantly (p<0.05) higher than that of the male
residents (13.53% and 13.64% respectively), with the female subject more impacted.
The mean Peak Expiratory Flow Rate was higher in male (11.06%) residents with
females (9.7%) more impacted. This study has shown that gender variation
impacted on cardiopulmonary parameters of residents in gas flaring communities
in south-south Nigeria

Background:Chronic
kidney disease (CKD) is a worldwide public health problem in the pediatric
population. Patients with CKD die of cardiovascular causes rather than from
renal disease. There are several traditional and non-traditional risk factors
for cardiovascular disease (CVD) in these patients. Endothelial dysfunction is
one of the non-traditional risk factors for CVD. Many studies have shown the
ability of omega-3 fatty acids to improve the endothelial function and reduce
the cardiovascular events in the general population. Thus, the aim of this
study was to evaluate the effect of omega-3 fatty acids supplementation on markers
of endothelial dysfunction in children with CKD on regular hemodialysis (HD). Methods and procedures:This
double-blinded randomized placebo-controlled trial included 49 pediatric
patients on maintenance HD. Group 1 (n=25) received 1 g omega-3 capsule once
daily and group 2 (n=24) received 1 g matched placebo capsule once daily. Both
groups were treated for four months. Blood samples were taken from patients of
both groups at baseline and after 4 months of supplementation. Serum samples
were examined for C-reactive protein (CRP) and nitric oxide (NO) levels as
markers of endothelial dysfunction.Results:Our
results showed that CRP was reduced insignificantly in omega-3 group. NO levels
showed no significant differences between groups at the end of the study.Conclusion: The administration of
1 g omega-3 capsule once daily for 4 months had no beneficial effects neither on CRP nor NO but should evaluate
more.

The present study tried to examine the relationship
between academic achievement and emotional intelligence, blocking the influence
of academic motivation on the relationship in secondary school students. Sample
for the study includes 49 students (25 girls and 24 boys) from VIIIth and IXth
classes of a secondary school in Sriram Nagar, Hyderabad, Telangana, India. The
data for measuring Emotional intelligence is collected by using the Trait
Emotional Intelligence Questionnaire – Adolescent Short Form (TEIQue-ASF), prepared by Petrides, K.
V. & Furnham,
A. (2006) for adolescents. The data for measuring
academic motivation is collected using Academic Motivation Scale, High School Version (AMS- HS 28) for high
school students prepared by Vallerand and et.al (1992). Academic achievement of the students is measured by
collecting the students’ grade point average in a summative assessment. For
data analysis, Pearson’s Product Moment and Partial Correlations are used. The
significance of the test is calculated by using t-test formula for partial
correlation for the level of significance α at 0.05. The findings of the study
reveal that the influences of academic motivation on the relationship between
academic achievement and emotional intelligence in secondary school students,
cannot be ignored.
